2. Discussion of the Related Art

Various services have been developed for a high-speed informationcommunication based on an ultra high-speed information networks. Theseservices range from simple methods [hear-speak] to complex multi-mediamethods [hear-watch-speak] using a digital terminal, which transmitsdocuments, sounds and images. It is envisioned that informationcommunication will routinely use a three-dimensional based service,which allows a user to observe a realistic stereoscopic image.

Generally, the three-dimensional stereoscopic images are obtained basedon a stereoscopic view by two eyes. Human eyes perceive views of theworld from two different perspectives due to their spatial separation.The spatial separation between the eyes of a typical individual is about65 mm. Due to the spatial separation between the left and right eyes,slightly different views are perceived, which is referred to asbinocular disparity. The three-dimensional stereoscopic image displaydevice uses the binocular disparity effect where the left eye perceivesonly the left-side view and the right eye perceives only the right-sideview.

The left and right eyes perceive two different two-dimensional images,and the two images are transmitted to the human brain by the retina. Thehuman brain then integrates the two images so as to reproduce therealistic and stereoscopic three-dimensional image, which is referred toas a stereography.

The technology of expressing the above-mentioned three-dimensionalstereoscopic images can be classified into a stereoscopic displaymethod, a volume measurement method and a hologram method. Furthermore,the stereoscopic display method is divided into a 3-D glass method andan auto-stereoscopic method based on whether special eyeglasses areadopted. The auto-stereoscopic method is further divided into a parallaxbarrier type and a lenticular type, on the basis of the structural shapeused to realize the 3D stereoscopic image. Hereinafter, the lenticulartype stereoscopic display method and apparatus will be explained.

FIG. 1 is a perspective view of a related art stereoscopic liquidcrystal display device of the lenticular type. FIG. 2 is a crosssectional view of FIG. 1. As shown in FIG. 1, the related artstereoscopic liquid crystal display device includes an LCD panel 10having lower and upper substrates 10 a and 10 b, a liquid crystal 10 cmaterial disposed between the lower and upper substrates 10 a and 10 b,and a backlight unit 20 to emit light to the LCD panel 10. The backlightunit 20 is positioned at the rear surface of LCD panel 10. A lenticularplate 30 is formed on the front surface of LCD panel 10 to develop thestereoscopic image.

Referring to FIG. 2, first and second polarizing sheets 11 and 12 areadhered to the upper surface of upper substrate 10 a and the lowersurface of lower substrate 10 b, respectively. The lenticular plate 30is formed by providing an embossing-pattern material layer on a flatsubstrate. As the image passes through the LCD panel 10 and thelenticular plate 30, different image groups are perceived by the leftand right eyes of the observer to facilitate perception of astereoscopic image.

For the related art stereoscopic liquid crystal display device, thelenticular plate 30 and the LCD panel 10 are supported by an apparatus(not shown). That is, the lenticular plate 30 is provided at apredetermined distance from the first polarizing sheet 11 of LCD panel10 with a spacing component therebetween configured to maintain thepredetermined distance between the lenticular plate 30 and the firstpolarizing sheet of LCD panel. It is necessary for the LCD panel 10,including the polarizing sheet, to remain flat. To accomplish this, thelenticular plate and the LCD panel are mechanically fixed or adhered toeach other.

In this case, the LCD panel 10 or lenticular plate 30 may sag or bendtoward the first polarizing sheet 11 of LCD panel 10. If the LCD panel10 or lenticular plate 30 sags or bends, an abnormal light passagecondition occurs from the backlight unit 20, through the LCD panel 10and the lenticular plate 30, thereby deteriorating the picture quality.This is especially true in the case of a large-sized LCD panel, wherethe LCD panel or lenticular plate may severely sag or bend due to itsown weight, whereby the picture quality may be reduced by crosstalk.

To decrease the space between the LCD panel 10 and the lenticular plate30, the LCD panel 10 and the lenticular plate 30 are fixed to each otherby an adhesive. In the case of large screens, a large amount of adhesiveis used, and transmittance of light is lowered due to the adhesive.

DETAILED DESCRIPTION

Reference will now be made in detail to exemplary embodiments, which areillustrated in the accompanying drawings. Wherever possible, the samereference numbers will be used throughout the drawings to refer to thesame or like parts. A stereoscopic liquid crystal display device, amethod of fabricating the display device, and a bonding apparatus usedto fabricate the display device, will be described with reference to theaccompanying drawings.

FIG. 3 is a plan view illustrating a stereoscopic liquid crystal displaydevice. FIG. 4 is a cross sectional view taken along line I-I′ of FIG.3. As shown in FIGS. 3 and 4, the stereoscopic liquid crystal displaydevice includes an LCD panel 1000 defining a display area 150 and anon-display area (the outside of the display area 150), a lenticularplate 300 positioned above the LCD panel 1000, and a sealant 400 formedin the non-display area between the LCD panel 1000 and the lenticularplate 300. Also included is an aperture or evacuation hole 450 formed inthe lenticular plate 300 between the sealant 400 and the boundary ofdisplay area 150, a finishing material (see 600 of FIG. 11) configuredto fill the evacuation hole 450, and an optical apparatus (not shown)positioned below the LCD panel 1000. The evacuation hole 450 provides anair conduit that communicates between the surfaces of the LCD panel andthe lenticular plate.

The LCD panel 1000 includes a first substrate 100, and a secondsubstrate 200 facing the first substrate. A sealing pattern (not shown)is formed along the perimeter of display area between the first andsecond substrates 100 and 200, and a layer of liquid crystal material170 fills the space between the first and second substrates 100 and 200.In addition, there are first and second polarizing sheets 111 and 112adhered to at least the display area 150 of the lower and upper surfacesof the LCD panel 1000, respectively. Also, the sealant 400 may be formedon the upper surface of the first polarizing sheet 111, or may be formedon the lower surface of the lenticular plate 300.

The lenticular plate 300 is formed of a glass substrate 301, and apolymer 302 with an embossing pattern is provided on the glass substrate301. Although not shown, the lenticular plate 300 may alternatively beformed only of the polymer 302, and without the glass substrate 301. Inthis case, the polymer has a predetermined thickness and is formed suchthat the lower part of the polymer is flat, and the upper part of thepolymer is embossed or patterned.

An evacuation hole 450 is formed through a portion of the lenticularplate 300 using a laser at a location inward of the sealant in thenon-display area. The size of evacuation hole 450 is determined based onthe distance between the LCD panel 1000 and the lenticular plate 300when the LCD panel 1000 and the lenticular plate 300 are bonded to eachother. The finishing material 600 used to fill the evacuation hole 450may be formed of the same material as that of the sealant 400, thepolymer 302 or the glass substrate 301. The sealant 400 is provided atfixed intervals along the four sides of the lenticular plate 300,wherein the sealant 400 is formed along a rectangular area, which issmaller than the lenticular plate 300. The sealant 400 forms aclosed-loop. The sealant 400 is preferably formed of a UV curablematerial. After bonding the lenticular plate 300 to the LCD panel 1000,the sealant 400 is cured by UV light.

Once the LCD panel 1000 and the lenticular plate 300 have been bonded,the evacuation hole 450 is connected with a vacuum jig provided in abonding apparatus. Air is evacuated from the space between the LCD panel1000 and the lenticular plate 300 through the evacuation hole 450. Afterthe air has been evacuated, the evacuation hole 450 is filled with thefinishing material. As a result, a stable vacuum is maintained betweenthe lenticular plate 300 and the LCD panel 1000.

Through the air evacuation process, the LCD panel 1000 and thelenticular plate 300 may be completely bonded to each other without thesmall gap, or may be bonded with the minute gap. In any case, the gapprovided between the LCD panel 1000 and the lenticular plate 300 issmaller than the initial gap provided prior to the evacuation of theair. As a result, after fabricating the stereoscopic liquid crystaldisplay device, it is possible to prevent the LCD panel 1000 orlenticular plate 300 from sagging or bending due to bonding and/orevacuation of air.

FIG. 5 is a plan view of illustrating a stereoscopic liquid crystaldisplay device according to a second embodiment. The stereoscopic liquidcrystal display device is similar in structure to the prior embodimentexcept for the inclusion of a sealant 401 provided adjacent to theperimeter of the lenticular plate 300 formed near evacuation hole 450,as shown in FIG. 5.

A predetermined portion of the sealant 401 corresponding to the locationof the evacuation hole 450 extends outwardly toward an peripheral edgeof lenticular plate 300. The extended portion is formed because theremay not be sufficient space to form the evacuation hole 450 between thesealant 400 and a display area 150 in the first embodiment.

Alternatively, the evacuation hole 450 may be formed in the sealant 400or 401. In this case, there is no laser-irradiation process for formingthe evacuation hole. The sealant material is provided except at theportion used to form the evacuation hole. Thus, the sealant may beformed as a thin line of material with a discontinuity or a smallportion missing. The vacuum jig then is positioned in the portion whereno sealant material exists so as to evacuate the air from between thelenticular plate 300 and the LCD panel 1000 to bond the lenticular plate300 to the LCD panel 1000. The finishing material then fills theevacuation hole in a similar way as described with respect to the firstand second embodiments. Accordingly, the sealant includes a firstpattern formed in the portions except at the location of the evacuationhole. A second pattern is formed only in area of the evacuation hole,where the first pattern is connected with the second pattern.

FIGS. 6A and 6B are plan views of a stereoscopic liquid crystal displaydevice according to third and fourth embodiments. The stereoscopicliquid crystal display devices are similar in structure to the devicesdescribed previously, and include a plurality of evacuation holes 451and 452 a.

The size and number of evacuation holes 451 and 452 a are determinedbased on a distance or gap between an LCD panel 1000 and a lenticularplate 300. As the number of evacuations holes 451 and 452 a increases,the speed of evacuating air from between the LCD panel 1000 and thelenticular plate 300 also increases.

FIG. 7 is a cross sectional view of a stereoscopic liquid crystaldisplay device according to a fifth embodiment. An evacuation hole 453is formed at an angle from a lower face of the lenticular plate 300 toan upper face of the lenticular plate 300. In the previous embodimentsdescribed, the evacuation holes 450, 451 and 452 a may also be formed atan angle.

FIG. 8 is a pictorial view of a bonding apparatus used to fabricate thestereoscopic liquid crystal display device. The bonding apparatusincludes a bonding part (not shown) to bond the lenticular plate 300 andthe LCD panel 1000 to each other with sealant 400. The bonding apparatusalso includes a pipe 510 connected to the evacuation hole 450, a vacuumpump 540 to pump the air evacuated through the pipe 510, and a vacuumtank 550 to store the air supplied through the pipe 540 so as todischarge the air to the external environment through an outlet.

The pipe 510, the vacuum pump 540 and the vacuum tank 550 constitute thevacuum jig. Alternatively, instead of providing a separate vacuum jig,the vacuum jig may be included in the bonding apparatus. Also, the pipe510 of vacuum jig is connected to the evacuation hole 450 during thebonding process, and is separated from the evacuation hole 450 after theair is discharged from between the LCD panel 1000 and the lenticularplate 300.

FIG. 9 is a flowchart illustrating a method of fabricating astereoscopic liquid crystal display device. FIGS. 10A-10C and 10E-10Gare cross sectional views, while FIG. 10D is a plan view, illustrating amethod of fabricating a stereoscopic liquid crystal display device. Thefabrication method of the stereoscopic liquid crystal display device iscarried out in accordance with the flowchart of FIG. 9, and thefabrication process is explained with reference to FIGS. 10A to 10G.

As shown in FIG. 10A, the LCD panel 1000 including the display area 150and the non-display area is formed (100S). The LCD panel 1000 includesthe first substrate 100, and the second substrate 200 facing the firstsubstrate. The seal pattern (not shown) is formed along a perimeter ofdisplay area between the first and second substrates 100 and 200. Theliquid crystal layer 170 is injected between the first and secondsubstrates 100 and 200 and sealed within by the seal. The LCD panel 1000is formed in the region including at least display area 150. Inaddition, the first and second polarizing sheets 111 and 112 are adheredto the lower and upper surfaces of LCD panel 1000, respectively. Thefirst and second polarizing sheets 111 and 112 may the same size as orlarger than the display area 150. The first and second polarizing sheets111 and 112 may be smaller than the lenticular plate 300 and the firstand second substrates 100 and 200 of LCD panel 1000.

Referring to FIG. 10B, the lenticular plate 300 is formed. Thelenticular plate 300 is larger than the display area 150, and is thesame or smaller in size than the LCD panel 1000 (110S). The lenticularplate 300 is formed of the glass substrate 301 and the polymer 302 withthe embossing pattern provided on the glass substrate 301. Although notshown, the lenticular plate 300 may be formed only with the polymer 302and without the glass substrate 301. In this case, the polymer has apredetermined thickness and has a flat lower surface and an embossedupper surface. Alternatively, the polymer may be formed only by theembossing-pattern shape without forming the flat lower part.

As shown in FIG. 10C, a laser is applied to the predetermined portion oflenticular plate 300 near an edge of the display area to form theevacuation hole 450 (120S). There may be one or more evacuation holes450. The size and number of evacuation holes 450 are determined based onthe distance between the LCD panel 1000 and the lenticular plate 300.The laser may be applied perpendicular to the face of the lenticularplate 300, or may be applied at an angle, as illustrated for example inFIG. 7.

As shown in FIG. 10D, the sealant 400 is applied to surround the displayarea 150. The sealant 400 may be formed on either the LCD panel 1000 orthe lenticular plate 300 (130S).

Referring to FIG. 10E, the LCD panel 1000 is bonded to the lenticularplate 300 by the sealant 400 (140S). Then, UV light is applied to thesealant 400 to cure the sealant 400. Ultraviolet light is used to curethe sealant 400 because heat-curing could deform the lenticular plate300. The evacuation hole 450, shown in FIG. 10F, of the lenticular plate300 meets with the vacuum jig provided in the bonding apparatus toevacuate the air from between the LCD panel 1000 and the lenticularplate 300 (150S).

The vacuum jig includes the pipe 510, the vacuum pump 540 and the vacuumtank 550. The pipe 510 of vacuum jig is connected to the evacuation hole450 in the process of bonding the LCD panel 1000 and the lenticularplate 300, and is removed from the evacuation hole 450 after the air isdischarged from the space between the LCD panel 1000 and the lenticularplate 300.

Regarding the air evacuation process, the lenticular plate 300 and theLCD panel 1000 may be completely bonded to each other, or a minute gapmay be maintained between the lenticular plate 300 and the LCD panel1000. Even though a minute gap may be maintained between the LCD panel1000 and the lenticular plate 300, the gap is relatively slight comparedwith the initial gap prior to the air evacuation process. As a result,after completing the stereoscopic liquid crystal display device, it ispossible to prevent the LCD panel 1000 or lenticular plate 300 fromsagging or bending.

By controlling the vacuum level during the air evacuation process, aminute gap may be maintained over the entire display area 150. Inanother aspect, when the LCD panel 1000 is completely bonded to thelenticular plate 300, the entire display area 150 is formed without thegap.

As shown in FIG. 10G, the evacuation hole 450 of lenticular plate 300 isfilled with the finishing material 600. The finishing material 600 maybe the same material as that of the sealant 400 or the lenticular plate300.

FIG. 11 is a plan view and a cross sectional view of a bonding method ofa liquid crystal panel and a lenticular plate in a stereoscopic liquidcrystal display device. The first to fifth embodiments described aboveshow that the sealant 400 is formed between the upper surface of firstpolarizing sheet and the lower surface of lenticular plate 300.

Alternatively, as shown in FIG. 11, a sealant 400 is formed between thelenticular plate 300 and the first substrate 100 of LCD panel. It ispossible to simplify an air-evacuation process due to a decreased gapbetween the lenticular plate 300 and a first polarizing sheet 111 a.

The first polarizing sheet 111 a is formed in a portion within theboundary of the sealant 400. That is, the sealant 400 is formed betweenthe first substrate 100 and the lenticular plate 300, and the spacebetween the lenticular plate 300 and the first polarizing sheet 111 a isdecreased in proportion to the thickness of first polarizing sheet 111a. Thus, the time required to evacuate the air is decreased. The firstpolarizing sheet 111 a may be the same as or slightly larger than thedisplay area 150.

After the air-evacuation process, the evacuation hole 454 is filled withthe finishing material 600. The finishing material 600 may be formed ofthe same material as that of the sealant 400 or the lenticular plate300. Because the evacuation hole 454 is formed in the non-display area,the finishing material 600 that fills the evacuation hole 454 has noeffect on the light leakage. The finishing material 600 may be formed ofa light-shielding material to prevent the reflection of light incidenton the lateral side of lenticular plate 300.

There may be one or more evacuation holes 454. The size and number ofevacuation holes are determined based on the gap between the lenticularplate 300 and the first polarizing sheet 111 a of LCD panel 1000. Asshown in the drawings, when the first polarizing sheet 111 a is bondedto the lenticular plate 300, there may be a minute gap along the entiredisplay area 150 between the first polarizing sheet 111 a and thelenticular plate 300. In another aspect, the first polarizing sheet 111a of LCD panel 1000 may be completely bonded to the lenticular plate 300so that there is no gap therebetween along the entire display area 150.The LCD panel 1000 according to the first to sixth embodiments may usean organic light-emitting diode (OLED), a plasma display panel (PDP) orother displays.

After the sealant material is formed on either the lenticular plate orthe LCD panel, the evacuation hole is formed in the lenticular plate. Aspace between the lenticular plate and the LCD panel may be maintainedunder the vacuum state by the decompression apparatus.

Even though a large amount of adhesive ingredient is not used in theprocess of bonding the LCD panel and the lenticular plate, the entiredisplay area is provided with the uniform gap, or no gap at all, betweenthe LCD panel and the lenticular plate, thereby preventing the LCD panelor lenticular plate from sagging or bending.

Instead of providing the additional vacuum jig to evacuate the airthrough the evacuation hole in the air-evacuation process, the bondingapparatus used to bond the LCD panel and the lenticular plate mayinclude the vacuum jig. This decreases the amount of time required tocarry out the air-evacuation process

The device and method disclosed above has been described with respect toan LCD flat panel display. The disclosed invention, however, may be usedwith other flat panel displays such as plasma displays, organic lightemitting diode displays, etc.
